Sentences with phrase «increase calcification rates»
In this study, averaged across all generation points, each coccolithophore cell increased its calcification rate (26 %) and calcium carbonate quota (26 %) in the future ocean treatment (figures 2a and 3a), and the total concentration of calcium carbonate in the culture (PIC l − 1) increased 18 % in the future ocean condition (table 4).

Previous studies showed that the coral calcification process has a diel rhythmic cycle of increasing rates towards midday, and then decreasing towards dusk (Gutner - Hoch et al., 2016; Schneider et al., 2009).
Reduced food supply owing to lower POC fluxes could exacerbate these impacts because the metabolic cost of increased rates of calcification become greater as pH declines (Wood et al., 2008).
Since you state that a decrease in net calcification could result from a decrease in gross calcification, an increase in dissolution rates, or both, you distinguish between these responses and get to the conclusion that the impact of ocean acidification on a creature's net calcification may be largely controlled by the status of its protective organic cover and that the net slowdown in skeletal growth under increased CO2 occurs not because these organisms are unable to calcify, but rather because their unprotected skeleton is dissolving faster.
They also point out that mutations that impair the «non-essential» vitamin K dependent proteins lead to bone fragility, arterial calcification, and increased cancer rates [3]-- all «age - related diseases.»
Lower calcification rates would reduce the alkalinity pump, reduce surface CO2 and increase the buffering capacity of surface waters.
Specifically, the increase in CO2 and HCO3 — availability might increase photosynthetic rates in some photosynthetic marine organisms, and the decrease in CO32 — availability for calcification makes
It is therefore unlikely that cell size is responsible for the increased PIC content and calcification rate in the future ocean treatment.
Cells increased inorganic carbon content and calcification rate under warm and acidified conditions compared with ambient conditions, whereas organic carbon content and primary production did not show any change.
For example, De Bodt et al. [22] found a 57 % increase in photosynthetic rate under elevated pCO2 that was non-statistically significant (table 6), whereas Langer et al. [15] found a 3 % increase in calcification rate under elevated pCO2 that was statistically significant (table 6).
